Be it kno-wn that I, JOSEPH C. Correze, a citizen of the Uni-ted Swim, residing at Willies-Bsrrs,l Luzerne v4Uounty, Pennsyl 5 venia, heve invented new and useful im proveniente 'Sign-Printing; Mechanisms, of which the foliowingis u specification.

In gone one of the special signtypes, as .the nonrrld eign' type, for instance, normally remains the printing line, so that it is only neeess-ery to provide means controlled by the non-edd mechanism, to effect non-accuniuietion on the counters, and to dis lace the individual dogwhieh normally loo s the sign. printing hammer against operation when the universel detent is released at each machine operation., v

The remaining special controlliii meehenisms, besides variously aifecting;u t e usuel operation of the machine, and tripping the' individual sign printing herinner dog, must also operate to shift the speial sign typecarrier to bring the appropriate sign type the printing line.

Naturally, assumingthut the u permost 1921. Berlu F0, 489,135.

ing line, the typecan'ier must vbe shifted progressively increasing distances to bring the suor'essive types below the uppermost type, to the printing line. Heretofore, the means which trips the individual dog for the sign printing hlmmer hns been shifted by the special Imechanisms which shift the t pecarrier, through substantially the sii/me (istance that the si 'printin typeoerrier is shifted, and disp aced the og when the sign type-carrier was shifted one step :is well as when the carrier was shifted ii greater number of steps.

In, adding an extraJ sign type, e nonu printk sign, to the number of sign types mounted in the typecarrier, it is obviously necessary for the non-print 'mechanism to ztotuitte the sign typeoarrier a. step fertlier than heretofore, in order to bring suoli odditional sign to the rintingI line.

Furthermore, t e total and sub-totali meehaii'iisms in the Wales machine nre so firranged that if an operntor eideiiteily or intentionallv depresses either of totii sub-total keys partwey only, the ineen will. either oe looked against o eration,

if operable, will either reset the to t? i* f idle positions, or shift them to their effen tive positions. y

Therefore, there is no liehiiity of pri t ing e non-add sign, for instance, opposite e total or sub-total amount, nor can n total sign to the printing line, and trip tlieiifr,

dividual locking dog to free the sign printinihammer.

ne object of the present inventioncis to insure that the non-print or'other sign wiil be properly positioned at the printing line to appropriately designate the non-print or other operation, and to prevent the operator from intentionally or accidentali mismanipulating the special keys whic control the specialfunctions of the machine end the printing of designating signs, to effect the printing Aof an inappropriate sign to designate an idle operation or an operation other than that which the mechanism controlled by the manipulated key is intended to vaccomplish.

To 'these and other ends, my invention includes severalnovel features and combinations, all of which will be more fully disclosed hereinafter and particularly pointed out in the claims.

ln the accompanying drawings, Fig. -1 is a 'longitudinal sectional View through a Anen-print key control thereof, the mechanism being in its normal idle position; and

Fig 3 is a similar view, showlng the positions of the parts when the non-print key has been depressed, the sign printing hammer being in discharged position` at the end of the forward stroke cf the machine.

i I have elected to show one embodiment ot my invention applied to the lVales calculating machine, examples of which are illustrated and described in U. S. patents to Wales #794,205, July 11, 1905; and #797,032, August 15, 1905;l yMcFarland #842,232, January 29, 1907: lVales #902,125, October 27, 1908; McFarland #924,264, June 8, 1909; and #1,024,013, April 23, 1912; Hunter & Kuntzler #1,054,554, February 25, 1913; Bickford #1,112,516, October 6, 1914; and Pentecost & Fisher, #1,355,253, October 12, 1920, to which reference is made for a more complete understanding of the Wales mechanisms.

The Wales machine includes a base 965 (Fig. 1) supporting the lside frames 967 which embrace a keyboard, an accumulating section and a printer section.

'Ihe numeral keys 11'7 forming a part of the keyboard, are arranged in denominational rows. Levers 116 individually connect the keys 117 with theircorresponding stops 115 also arranged in denominational tiles, in line with the paths. of denomina-4 tional adding racks or drive members 310.

, A rack detent 221 journaled on a cross shaft 202, overlies each file of stops 115, andv projects slightly rearwardly thereof, to arrest the racks 310 during an operation of the machine, when no keys and stops in the denominational files corresponding with the racks, have been operated.

The racks 310 are each pivotally mounted on individual front and y,rear supporting arms 312 and 311, respectively, the front arms312 being journaled on across shaft 300 andthe rear arms 311 logn-a cross rod 301.

Springs 383 connect the rearv supporting arms 311. of the res ective racks 310, withl a transversely exten ing restraining and restoring bar 205 mounted in lingers 265m depending from a rock shaft 265 journaled in the side. frames 967 and oscillated from the main drive shaft 200 by means, not herein shown, but fully ydisclosed'in the patents above mentioned.

Denominational counters 490 independently journaled on an axle 400 extending transversely-ot` the machine above the adding racks or drivemembers 310, each have associated therewith a pinion 435 adapted to engage with and disengage from its respective rack 310. Arms 322 pivoted at 9.52d to the side frames 967, support the axle 400 with the counters 490 and pinions 435, the counters and their pinions being normally held out of mesh with the racks 310, by means of props 319 pivotcd at their upper ends, at 357, to the arms 322, and being slotted at their lower ends to embrace and rest upon the oscillatory counter-engaging and disengaging bar 303 mounted in radius arms 323 journaled on the shaft 300. Links 214 connect the bar303. with cranks 212 fast on the 'main drive shaft 200, which is held in its normal position by the usual main restoring springs 285, the bar 303, in consequence, being held at the upper end of its arcuate path of travel.

Depression of the numeral 'keys 117 in the various denominational rows corresponding with the digits of the amount to be registered on the counters 490,v in an adding operation, projects the appropriate stops 115 into the paths of ,the corresponding denominational racks 310, Ythe projected stops 115 displacin the corresponding rack detents 221, an being releasably held projected by the usual latches 114.

Advancing the main drive shaft 200 on its forward stroke in any suitable manner, against the tension of restoring sprn y 285` operates the customary and well-snown Wales mechanism` (not shown) to rockv the shaftl 265 and the fingers 265' and withdraw the universal bail 205 from its rehe main drive shaft 200, on its forwardstroke,also rocks cranks 212 to draw the links 214 forwardly and swing the counterengaging and disenga'ging bar 303 on its.

downward arc of travel, thereby relieving the arms 322 of the support afforded by the 1 props 3191 Removing they support of the props 319 vfrom the armsv 322 would rmit the synchronous descent of the axle 400 with its counters 490 to-mesh the pinions 435 with the racks 310,.were itinot for the provision .Mofalegs-316' depending from the projecting Dit Lsa.

ends of the axleh400, lthe legs .having feet at their lower ends lying in line with rests 958, and adapted to contact with such rests at the outset of the attempted descent of the axle 400, to maintain the counters 490 and their pinions 435 out of mesh with the racks -'310 until therlatter have completed their ad vance. Bridle links r321 connected to the legs 316 are slotted to embrace the counterengaging and disengagin bar 303, which, as it progresses on its ownward arcuate ath, idly traverses the slots in the bridle links 321 and props 319 until, near the end of the forward stroke of the main drive shaft, the bar 303 contacts with the outer end walls ofthe slots in the bridle links 321 to trip the legs 316 olf of the rests 958% whereu on, the axle 400, with its counters 490 and) pinions 435, quickly drops to mesh the pinions with the advanced racks 310.

Atthe end of itsforward stroke, the main drive shaft 200 is released. to the action of its restoring springs '285, which return the shaft to lits normal or home position.

The main drive shaft, on such return, through the usual mechanism (not shown) presses the universal restraining and restor-` ing bail 205 against the front arms 312 of the advanced adding racks 310 to return them to normal position, the racks 310 dur ing such return, operating to turn the pin.n ions 435 mashed therewith and the counters 490, to register thereon the amount set up on the keyboard and represented by the depressed keys 11i'. ,v At the same time, the counter-engaging; and disengaging bar 303 is being returned through cranks 212 and links 214 along its upward arcuate path, the bar dlytraversing the siots in the bridle 'links 321 and props 319 uni-ii, nea-r the end of the return. stroke of theinain drive shaft, and after the racks' 310 have been restored to their home positions, the har 303 contacts with the upper endsof the slots in the props 319 to lift theaxle 400 and thereby disengage the inions 435 from the drive members 310. he legs 313 rise with the axle and as soon as their feet clear the rests 958, springs 385i operate to snap the leo's into line with suchA rests prearatory to the next operation.

-Suitab e means (not shown) also operates automatically te displace the latches 114 and enable the 'proiected stops 115 andl depressed keys 117 to restore-to normal position.

`Printing of the amount set up on the keyrd occurs near the end of the forward 'stroke of the main drive shaft 200, and is fprovided for as follows:

project rearrear rack-su Converging levers 311' 5 tothe corres ndicng denominational ,typecarriers 514, -in the heads of which types against the paper on ylease the ears 513m typecariiers are mounted the types 561 arranged in vertical rows commencing at the upper end with 0 and terminating with 9 at the lower end. The cipher types lie just 'below the )rinting line of the platen 2094, and the a vance of the racks or drive' members 31() until they contact with the rack-arresting detents 221, positions the cipher types at the printing line. The racks 310, when advanced until the contact with the l key-set stops 115, li t the typecarriers a ste farther to position the 1 types at the printing line, and so on. Printing hammers 510, by their impact against spring-retracted firing pins 562 located in line with the type stems when the t pes 561 are positioned at the printinv` line, rive the the platen 2094.

ie denominational printing hammers 510 are actuated bysprings 580 suitably tensioned just prior to the time of hammers being reset or cocked operated in a manner usual in the Wales machines, on the return stroke of the main drive shaft 200.

A universal latch 518 carried by a shaft 502. normally retains the hammers 510 in coc .ed position durinfr the forward stroke of the main drive shaft, at which time the cooking bail 505d is being withdrawn from the paths of the hammers, and in addition, the hammers are locked against operation by individual does 511 iournaled on a cross rod 50e, and he d in effective position by springs 581.

Trip bars 513 coast with cach dog 511., to reiease the latter, the bars being pressed against the tails. of their respective dogs 511, hy springs 583, and having .sterol ears 513m extending beneath their respective converging levers 311m.

The levers 311' when in their normal lowered. position, Contact with the ears 513m of the trip bars 513 to retain the latter in their lowered. idle positions against the tensions of their springs 583. As the converging levers 311m swing upwardly due to the adiring, they vance of the corresponding drive members y 310 against the progiected stops 115, they reand the trip bars 513 to springs 583, which raise causing the upper ends of such the action of their the trip bars,

bars to contact withthe tails of the correi spending individual dogs 511 and rock the dogs to idle position, thereby freeing the correspondin hammers 510 for operation as soon as re eased by the universailatch 518.

As the main` drive shaft 200 approaches the end of its forward; stroke, it operates mechanism well known in the Wales machine and disclosedI in' the patents above referred to, to lift the universal latch 518 i' i .to idle position, thereby freeing those hammers -510 which have been released' by their individual dogs '511,

for operation, the revco leased hammers driving the//firingpins 562b against the types 561 positioned at the printing line.

Advancement' of the racks 310 to position the cipher types at the printing line is not suiicient to enable the trip bars 513 to trip their individual dogs 511, but each dog is provided with the usual cross-over iinger to enable the printing of ciphers to the right of the digit of highest value, in the customary manner.

lThe main drive shaft 200 onf its return stroke, swings the resetting bail 505d forwardly, to recock the discharged hammers, which, when restored to set position, enable the universal ,latch 518 to snap back to effective position to temporarily hold the hammers cocked while theresetting bail is heilig withdrawn on the next forward stroke yol" the main drive shaft.

ytact with vthe individual dogs 511, which thereupon swing upwardly under the in fiuence of their springs 581, to lock the denominational hammers 510 in cocked position. l t

To print a total of the amounts accumulated on the counters 490 and clear the counters, the operator depresses a total and clearing key 327 rel'easabl connected by a latch 326, to the forwardly extending arm of a set lever 317b fast on the cross shaft 300. A link 315 connects the upwardly extending arm of the set lever 317b with the leg 316, the set lever and link being duplicated on the opposite side of the machine, so .that upon operation of the set levers, the detaining legs 316 are displaced relatively to their rests 958, and as a consequence, the counters 490 and their pinions 435 drop into mesh with theirdrive members 310 at the begi ning of the forward stroke of the main drive shaft 200, to enable the drive members to reversely rotate the counters 490 to'their zero positions, during the ad- .vance of the drive members as is common in the 'Wales machines and clearlyfset forth in the prior patents referred to, so that further explanation is unnecessary. The drive members 310 in this operation are under the control 'of the counters 490 and positionV types at the printing line cor'-, responding to the amount registered on the counters, the hammers `51() operating to impress the t pes on the paper* as ex lainedl y p. tadispiathe indivi ualdqgs 511,:he1ato record such total amount.

At the beginning of` the return stroke of the main drive shaft in totaling operations, means (not shown) effects the disengagement of the counters 490 and their pinions 435 from the drive members 310 prior to the return of the latter to home position, whereby the counters remain at zero while the drive members return to their normal positions of rest.

Depression of a sub-total key 327b opcrates the set lever 317 as does the total and clearing ke 327, to trip the detaining legs 316 to enab e the counters 490 and their pinions 435 to mesh with the drive members 310 prior to the advance of the latter. As the drive members advance, they reversely rotate the counters to their zero positions, and-set the types to represent the amount registered bythe counters, which is printed, asvusual, near the end of the forward stroke of the main drive shaft. p The counters are not disengaged from their. drive members, however, until near the end of the return stroke of the main' drive shaft, and hence the drive members 310, as they restore to normal position, turn the counters to cause theml to again register the amount previously displayed thereon.

Sometimes it is desired to print a number without registering it on the counters, which operation is effected by preventing the engagement of the `counters 490 and pinions` 435 with their racks, in a manner Well known in the art andlidisclosed, for example, inv patent to McFarland, #1,024,013, dated April 13, 1912. Q

Also, it often happens that the operator wishes to add an amount on the counters 490 without printing` the same. Depression of key 526b (Figs. 2 and 3) projecting through an aperture in the case 1065 of the machine and through a slotted scutcheon plate' 1018d covering such aperture, -depresses a short link 419 over which the hollow sleeve of the key 526 fits.

The link 419 is pivotally connected to a key stem 5231v by a slot and pin connection 458. A spring. 582 connected to the link 419 and to the pin 458 in the stem 523", holds the link at the upper limit of its travel as determined by the slot therein. Depression of the link 419 depresses the key stem 523bconnected at its lower end at 562t to an arm projecting forwardly from one side `of a 'substantially U-shaped rocking comb 524l having teeth 524, and ivotally mounted on a cross rod 506, to s ift the teeth of the comb into the paths of shoulders 513 formedv on the lower ends ofthetrip bars' 513 associated with the individual dogs 511 of the denominational printing hammers 510, and this locks the trip bars 513 against operation. l

Obviously, if the tri bars 513 do not rise eil'ect on the operation of the drive members 310, which, during the operation of the main shaft 200 on its forward and return strokes. lift thetype bars 514 to position the types at the printing line, register the amount onl the counters 490 and return the type bars 514 to their home positions.

Releasing the non-print key 526h enables the restoring spring 589b connected to the stem 523", to return the non-print comb 524L to idle position, and restore the key to its normal elevated position.

The foregoing mechanisms are usual in the Wales machine and form no part of the present invention, except in so far as they coact therewith to produce the various results hereinafter explained.

It has been customary, in theWVales-machine, to arrange for the rinting of various signs to designate non-adr?, totaling, and subtotaling operations, and to this end, it is usual to provide a special typecarrier 514' (Figs. 2 and 3) in which are mounted the non-add sign printing type 561", the total sign printing type 561x, and the sub-total sign printing type 561. The non-add type 561"1s usually at the upper end ofthe typecarrier 514m, and normally lies opposite the printing line on the platen 2094, as shown in ig. 2. Depreion of a non-add key (not shown) trips the individual hammer-locking dog 511", against the tension of its spring 581, by means common to the Wales machine, so that upon the withdrawal of the hammer-resettingbail 505, and the release of, the universal latch 518, a sign printing hammer 517, similar to the regular printing hammers 510. will drive its firing pin 562b against the type stein 561" to impress the non-add sign type on the paper as an incident to the printing of the non-added amount.

It will be noted that no adjustment of the sign typecarrier 514m is necessary to position the non-add sign at the printing line, but it is neceary to provide means to adjust the remaining signs relatively to the printing line, as well as to provide means to'release the individual dog 511 from the sign printing hammer 517 'Thus. depression of.l the total key 327 (Fig. 1') for instance, causes a stud 344y mounted on the lower end of the total vkey stem to wipe along a cam edge 326m formed on a slide 326d extending along the base of the machine from front to rear, the rear end of the slide being connected to a crank 1814 fast on a cross shaft 1801. Contact of the wiping stud 344 with. the cam edge 326n shifts the slide 326'l rearwardly against the tension of a return spring 682Il to rock the shaft 1801, which shaft carries an arm 1814. A ylifting pin 963 projecting laterally from the arm 1814*"lextends beneath the foot 516 (Fi 2 and 3) of a special vertically exvten ing tri bar 516, `the up r end of which is a apted to contact w1th the tail of the sign printing hammer dog 511' to disable the dog, so-that the hammer 517 can operate upon the withdrawal of the re-A setting bail 505d and the displacement of the universal latch 518. Allink 515 carries at itsupper end a pin 550' slidable in a slot 516" formed intermediate the ends of the trip bar 516g, the opposite end of the link being connected to the special sign typecarrier 514'n similarly to the regular or denominational typecarriers 514. cured at one end to the pinl 550m, normally retains the latter at the lower end of its' slot 5161 and also maintains the trip bar516 in its lowered idle position with its foot 516m resting upon the operating pin 963 in the arm 1814", the special sign typecarrier being thus returned to its, normal lowered position, wherein the non-add sign 561' is located at the printing line.

Rocking the cross shaft 1801 by the depression of the total keyv 327, rocks the arm 1814* to press the pin 963 against the foot 516m of the trip bar 516', lifting the trip bar to displace the individual dog 511, that has held the sign printing hammer 517* against operation, the elevation of the trip bar 516 o erating to bring the lower end wall of the s ot 516 in the trip bar 516 against-the pin 550', to lift the link 515 and with it the sign typecarrier 514m, to position the total sign type 561 at the printing line.

Operation of the main drive shaft 200 releases the hammer 517* for operation, as heretofore set forth, and near the end of the return stroke of the main drive. shaft. the

'wiper stud 344 (Fig. 1) withdraws from contact with the cam edge 326m to free the slide 326d to the action of its restoring spring tions.v The trip bar 516' by its return, rel leases the individual dog 511 to the action of its `spring 581t which restores the dog to locking engagement with the sign type printing hammer 517, the latter having been recocked by the bail 5051fduring' the return stroke of the mai-n drive shaft.

Depression of the sub-total key 327 (Fig. 1) wipes a stud 344m on the lower end of its keystem, along a cam edge 326 on the slide 326, the cam edge 3261 being of greater extent, or, it may be, of av greater pitch than A spring 581", sev the cam edge 326m, whereby the slide 326'?` is shifted farther than when the total key 327 is depressed, to rock the arm 1811ib through a greater angular distance and cause it to lift the trip bar 51.6? (Figs. and 3 and lthe sign typecarrier 514m to a higher point, than when these parts are operated by the total key.

substantially as set forth in connection with the total key. y

Means are associated `With'both the total and sub-total keys to prevent accidental or intentional mismanipulation of the keys, as set forth in the patents to McFarland #842,232, January 29, 1907; and Pentecost & Fisher #1,355,258, October 12, 1920, so`

that a partial depression of either key followed b1 an operation of the main drive shaft wi l result either in automatically completely depressing the key or in restoring it to idle position, and hence the proper sign will be located at the printing line, or an idle operation will take place.

The non-print sign type 561z is the lowest of the four sign types, and 'it is necessary to lift the typecarrier 514:m three steps to y bring the non-print type to the printing line,

and consequently it would also be necessary to impart a similar throw to the trip bar 516g. But the non-print key 526 is coinpletely under the control of the operator, and if the key was positivelyvconnected with the sign typecarrier 514m, the partial depresion of the key, either accidentally or intentionally, would lift the sign typecarrier 'partway only, and effect the imprint of a sign other than the correct sign designating a non-print operation.

To reduce the liability of occurrence of such contingency, l preferably arrange suitably timed means controlled by the nonprint key 526b to operate the trip bar 516g only as the non-print sign type 561Z is brought to the printing line. and the nonprint comb 524ea reaches its fully operative position.

To these ends, l provide means to be controlled by the non-print mechanism, other than the arm 1811ib and lifting stud 963, to operate the sign typecarrier 514m and the trip bar 516g.

Referring to Figs. 2 and 3, it will be noted that the non-print .comb member 524al carries a rearwardly extending arm 524:X preferably having a concaved upper edge adapted to` contact with the convex end of the depending arm of a bell crank 524xn pivotally mounted at5501. The forwardly extending arm of the bell crank 524m projects beneathv the pin 550m carried by the link 515 whichconnects the trip bar 516.s and the sign typecarrier 514m, such pin entering the slot 516p in the trip bai'. V

Depressing the non-print key 526b and its stem 523h against the tension of its restoring l spring 589", rocks the non-print comb 5211a and swings the arm 524x thereof upwardly against the camined end of the bell crank lever 524;m to turn thellatter.- The forwardly extending arm of the bell crank lever 524m immediately' contacts, with the pin 550m and lifts thelatter, together vwith its link 515 andsign typecarrier 514m, to shift the non-*print sign type 561z towards the print- .ing lineon the platen 2094, independently of the trip bar 516g, the pin 550m traversing the slot 516p in the trip bar especially provided for this operation. t

The non-print comb 524 also commences its travel towards its operative position, but does not become immediately effective.`

At about the time when the sign type 561y just above the sign type 561", is substantially located at the printing line, the pin 550m contacts with the upper end of the slot 5161 in the trip bar 516g and the farther depression of the key 526b operates through the comb 5243, arm 524x, bell crank 524m 'and pin 550m to lift the trip bar 516g together with the sign typecarrier 514m, to displace the individual hammer-locking dog 511 and also to locate the non-print sign 561z atthe printing line, the comb 524a shifting to its fully edective position.

With the non-print mechanism set, operation of the main drive shaft '200 (F ig. 1) will advance the racks 310, and position the denominational type bars 514 in accordance with the amount set up on the keyboard. but the comb 524, by restraining 513 against the vaction Iof their springs 583, prevents the trip bars from releasing the individual dogs 511 from their denominational hammers 510, and consequently, although the universal hammer latch 518 shifts to idle position no amount will be printed. The non-print sign 5611, however, will be printed because the hammers 510 will be held in cocked position by their individual dogs 511 to designate that an adding operation without a corresponding printing operation has taken place, the sign printing trip bar 516g having no shoulder 513D, and hence the nonprint print comb 524*l has `no control thereof.

the trip bars Complete depression of the non-print ke 526b followed by its partial release wi l merely permit spring 589 to withdraw the comb 524* to ineffective position, and spring 581x will ldraw the trip bar 516 downwardly f to release the dog` 511 for operation, and though the sign typecarrier 514mIwi1l have only partially descended, the sign printing hammer 517* will be locked by its dog 511 to prevent the printing of an incorrect sign.

Furthermore, by arranging to delay lthe action ofthe trip bar 511 on the dog 511e by the lost motion connection comprisin the stlidG and the slot 516?, the, do 1s not displaced to an excessive extent W ien the non-print sign type 561z is brought to the printing line.
